Design overview of a rapid mapping resolution system for enabling identifier/location separation in satellite network

The current satellite network design is approaching an inflection point with mobile devices as the primary enduser devices. In addition, identifier/location separation is commonly used to enhance mobility in future satellite networks. To this end, a key issue must be addressed is the design of rapid mapping resolution system. In this work, a design overview of a rapid mapping resolution system is presented. Two key design elements, the space-based distributed design as well as the dynamic replica placement algorithm are also described to achieve the goals including low lookup latency, low update cost and high system availability.
